See What Our Patients Say About This Location:
I have been a Smile Agency patient for over 10 years. I trust Dr. Guinn with all my oral cosmetic needs. The office just received an amazing renovation and is sparking clean and vibrant. The staff is attentive and friendly. I was helped by Jocelyn and Allie who did a wonderful job prepping me for my laser gum removal. The entire process from beginning to end was easy and pain free. Dr. Guinn was so pleasant and professional, as always. I recommend the Smile Agency to all of my friends and family and anyone in the San Gabriel Valley.

Great place for adults who need braces too. Excellent customer service. Dana, who I believe is a manager at the Sunset location, is the best!

I called a couple places for consultations on braces, and even went into a few locations and I was unhappy each time I left a location... Until I came across The Smile Agency. I can say that I honestly lucked out by reaching out to them! I came to them because of their amazing reviews and they seriously live up to their reviews and more! Dana sold me with her incredible kindness, silly personality, and her genuine caring nature. Mark has been my go to guy throughout my treatment, and as I think everyone here is absolutely lovely to talk to and has been nothing but helpful and kind, Mark has been incredible with answering all of my paranoid questions, listening to my concerns and explaining to me everything that's happening every single visit. Dr. Guinn is the glue to the crazy funny, friendly, and knowledgeable staff they have here. You can tell she not only knows what she's doing and talking about, she genuinely cares not only for her patients, but about her staff and to me that's HUGE. The vibes around the office are fun and friendly, I can honestly say I've never laughed and smiled and as often as I do here than any other dental office. Who says that?!

Dr. Guinn is nothing short of amazing! She makes you feel comfortable and it’s almost like she’s a friend or family member. My teeth are almost perfect thanks to her and her wonderful staff! Mark especially. From the warm and inviting offices to the friendly and helpful staff. Dana from the West Covina office has been an angel since day one and I appreciate her so much. The girls at the front desk in Pasadena are so nice every time I see them. They always accommodate me even when I’m late! I highly recommend Smile agency to everyone looking for a perfect smile!

Dear Smile Agency, Thank you very much for fixing my teeth for these past 2 years. My orthodontist for this visit was Mark and he was very considerate to answer all of my questions, take time off from wearing my braces and move onto the next step for teeth straightening, and give me new bands for my teeth. Sadly, our time together is almost over and I am going to miss all of your bright and positive attitudes. Once again, thank you so much for everything you've done for me over these past 2 years. You've done a great job and if any of my friends need braces, I will definitely recommend them to Smile Agency at West Covina office. Sincerely, Eric Tran
